Zhiyu666 vertical blind weights and chains set (50 weights + 20m chain) for 89mm slats

What it is and why people buy it

This Zhiyu666 set is made for repairing or refreshing vertical blinds where the slats no longer hang neatly or the ladder action feels off. In simple terms, it replaces the small bottom weights and the chain that helps keep the slats aligned and moving together.

On paper, the kit is aimed at the “DIY fix” crowd: people who don’t want to swap the whole blind just because the slats are misbehaving. The bundle includes 50 bottom weights and 20 metres of chain, and it’s specified for vertical blind slats at 89mm (3.5 inches). It’s the kind of accessory set you keep in mind when you’re trying to restore consistent light control and a tidy look.

A practical micro-scenario: if you notice one or two slats hanging unevenly, or the chain side doesn’t glide smoothly, replacing the worn weights/chain can help the slats stop tangling and return to a more predictable movement.

The essentials (what you’ll notice in day-to-day use)

The main job of vertical blind weights is to keep each slat properly weighted so it hangs flat instead of twisting or bunching. According to the product description, these are designed to be stabilising, which should reduce the chance of slats tangling. The chain is positioned as “smooth-gliding” to help the slats move more consistently.

There’s also a maintenance angle: the chain is described as rust-resistant. That matters most if your blinds sit near a kitchen, a busy corridor, or anywhere with a bit more humidity over time.

Still, it’s worth setting expectations: this is an accessory kit, not a full replacement blind system. If your problem is caused by a larger mechanism issue (headrail, drum, or bracket problems), the weights and chain may not fix everything.

Key features that matter for replacements

A few details in the description are clearly aimed at compatibility and ease:

• Designed as vertical blind slat accessories for replacement/repair rather than a brand-new installation.
• The weights are described as compact and discreet, so they don’t look overly bulky on the bottom of the slats.
• The chain is highlighted as durable and rust-resistant, which is more reassuring for long-term use.
• Installation is presented as quick and tool-free, which can be a big deal if you’re doing a same-day repair.

One limitation to keep in mind: the listing claims it should suit most standard replacement vertical blind slats, but it also strongly specifies 89mm slats. If your slats aren’t that size, you’ll want to avoid guessing.

How to get the best results before you buy

Before committing, double-check the measurements and what part of the blind you’re trying to fix. The kit mentions 89mm (3.5 inches) and focuses on bottom weights and the chain that helps the slats stay stable.

Here’s what tends to reduce “returns for the wrong reason”:

• Confirm your slat width is 89mm (3.5 inches). This is the clearest compatibility signal provided.
• Think about whether you need just some replacements or a fuller refresh. With 50 weights, this set is naturally suited to blinds with multiple slats rather than a single broken piece.
• Consider whether the movement problem is likely chain/weight related (slats drifting, uneven hanging, tangling) versus a headrail mechanism issue.

If you can’t confidently match the slat size, it may be better to look for a kit that explicitly matches your blind’s slat dimensions—vertical blinds can be surprisingly particular.

Who it suits (and when it may not)

It’s a sensible buy if you’re dealing with worn or damaged vertical blind slats and want to restore privacy and light control without replacing the entire unit. The “replacement vertical blind slats kit” positioning suggests it’s meant to slot into the existing system.

It’s less ideal if:

• Your slat size isn’t 89mm (3.5 inches).
• The issue is coming from the headrail, tilt mechanism, or brackets rather than the weights and chain.
• You’re looking for a brand-new upgrade feature set—this is more about restoring function than redesigning your blinds.

Is it worth it?

Worth considering if you want a straightforward, tool-free DIY way to stabilise vertical blind slats—especially if the description’s problems (uneven hanging, tangling) match what you’re seeing.

You may want to skip it if you can’t verify that your slats are 89mm (3.5 inches), or if the blind’s movement problem is likely mechanical beyond the weights and chain. In those cases, buying this accessory kit alone could feel like solving the symptom rather than the cause.

Quick check of price and value trends can also help, because replacement parts are often only “good value” when they genuinely match your blind’s dimensions and the number of slats you need to service.

FAQ

Will this work with most vertical blinds?

The kit is described as being compatible with most standard replacement vertical blind slats, but it also specifically calls out 89mm (3.5 inches). In practice, slat size matching is what you should prioritise.

Does it include everything needed for a basic repair?

The set includes 50 bottom weights and 20 metres of chain, which should cover the typical “slat accessory” side of a repair. It does not claim to include the headrail mechanism.

Is installation really tool-free?

The description says there are no tools required for quick installation. That said, your exact process will still depend on how your current slats are set up.

What if my vertical blinds still don’t move smoothly?

If the slats struggle after replacing the weights/chain, the issue may be elsewhere in the blind system (for example, the headrail components). In that case, this kit might not be the full solution.

How can I tell how many weights I need?

With 50 weights included, you’re likely aiming to replace weights across multiple slats. If you only have one or two damaged slats, you may find the full set more than you need.
